1. Chemical Bonds

2. Ionic Bonds What is an Ionic Bond?
- An Ionic Bond is a chemical bond resulting from the TRANSFER of electrons from one bonding atom to another
When is an ionic bond formed?
- An ionic bond is formed when a cation (positive ion) transfers electrons to an anion (negative ion).

3. Charged Atoms When atoms lose electrons they become positively charged
When they gain an electron they become negatively charged
A negatively charged atom and a positively charged atom will be attracted to each other

4. Charges of Atoms
+1, , +/-4, -3, -2, -1,+/-0

5. What are some characteristics of an ionic bond?
Crystalline at room temperatures
Have higher melting points and boiling points compared to covalent compounds
Conduct electrical current in molten or solution state but not in the solid state
Polar bonds

6. Covalent Bonds What is an Covalent Bond?
Will not conduct!
What is an Covalent Bond?
- A covalent bond is a chemical bond resulting from SHARING of electrons between 2 bonding atoms.
What forms a covalent bond?
- A covalent bond is formed between two nonmetals.

7. What are some characteristics of a covalent bond?
Covalent bonds have definite and predictable shapes.
Very strong
Low melting and boiling points

8. Covalent Bonds can have multiple bonds, so you should be familiar with the following…
Single Covalent Bond- chemical bond resulting from sharing of an electron pair between two atoms.
Double Covalent Bond- chemical bond resulting from sharing of two electron pairs between two atoms.
Triple Covalent Bond-chemical bond resulting from sharing of three electron pairs between two atoms.

9. First, we are going to look at Polar Covalent…
What is polar covalent?
-Polar covalent is a description of a bond that has an uneven distribution of charge due to an unequal sharing of bonding electrons.
The boy is not equally sharing with anyone else but rather taking all the food for himself.

10. Next, we are going to look at Non-Polar Covalent…
What is non-polar covalent?
-Non polar covalent is a covalent bond that has an even distribution of charge due to an equal sharing of bonding electrons.
This couple is non- polar because they are sharing the drink equally between them.

11. Just as a summary to what each bond looks like…
